Problems solved by technology

[0002] High-frequency cables are cables used to transmit high-frequency signals. Since the cables have distributed capacitance and distributed inductance, they can filter high-frequency signals and attenuate high-frequency signals. Therefore, for the transmission of high-frequency signals, distributed capacitance and distributed inductance are required. Small cables, whose insulation and sheath materials are polyvinyl chloride, cannot meet the needs of those who need to use in high temperature environments, and their firmness is not strong

Abstract

The invention discloses a fireproof and refractory Litz wire high-frequency special cable, which includes a cable core, and is characterized in that: the cable core includes an I-shaped silicone rubber skeleton, and two Conductor groups, each of which includes two litz wire conductors twisted by several enameled wires, and the outside of the litz wire conductors formed by twisted enameled wires is covered with a silicone rubber insulating layer; each of the The outside of the conductor group is sequentially covered with ceramic silicone fireproof composite tape inner wrapping layer and metal wire braided shielding layer from inside to outside, and the cable core is sequentially wrapped with ceramic silicone fireproof composite tape outer wrapping layer, mica layer, Fireproof sheath. The insulating layer and skeleton of the present invention are made of silicone rubber material with good high temperature resistance, which can meet the high temperature environment where the working temperature of the cable is 180°C, and the use of the skeleton further meets the requirements of the firmness and drag resistance of the cable. need.

Description

Technical field [0001] The present invention relates to the field of cables, in particular to a fireproof and refractory Leeds wire high frequency special cable. Background [0002] High-frequency cable is used to transmit high-frequency signal cable, because the cable has a distributed capacitance and distributed inductance, the high-frequency signal has a filtering effect and the high-frequency signal attenuation, so for the transmission of high-frequency signals, the need for distributed capacitance and distribution inductance of small cables, its insulation and sheathing materials are polyvinyl chloride, can not meet those who need to use in high-temperature environments, and its firmness is not strong. [0003] PTFE, commonly known as the "Plastic King", is a polymer compound made of tetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stick, electrical insulation and good anti-aging endurance. Used as engineeri...
